The only reason Google think we do is because they implemented AdSense incorrectly. E.g. Using an impractical and underpriced PPC model. If they used a fixed pricing model this would not be a problem, and fake clicks would not even be an issue.
The site claims they get 1M visitors per day; should an advertiser believe them?
I am reminded of a story of a retailer who adódnak l accidently stopped advertising online and so no adverse change in sales. While I can't find the exact one I have in mind, it seems this isn't rare.
